I’m writing a feature in cucumber that could be applied to a number of objects that can be programmaticaly determined. Specifically, I’m writing a smoke test for a cloud deployment (though the problem is with cucumber, not the cloud tools, thus stack overflow).
Given a node matching "role:foo"
When I connect to "automatic.eucalyptus.public_ipv4" on port "default.foo.port"
Then I should see "Hello"
The given does a search for nodes with the role foo does and the automatic.eucalyptus… And port come from the node found. This works just fine… for one node.
The search could retun multiple nodes in different environments. Dev will probably return one, test and integration a couple, and prod can vary. The given already finds all of them.
Looping over the nodes in each step doesn’t really work. If any one failed in the When, the whole thing would fail. I’ve looked at scenarios and cucumber-iterate, but both seem to assume that all scenarios are predefined rather than programmatically looked up.
I’m a cuke noob, so I’m probably missing something. Any thoughts?
Edit
I’m “resolving” the problem by flipping the scenario. I’m trying to integrate into a larger cluster definition language to define repeatedly call the feature by passing the info as an environment variable.
I apologize in advance that I can’t tell you exactly “how” to do it, but a friend of mine solved a similar problem using a somewhat unorthodox technique. He runs scenarios that write out scenarios to be run later. The gem he wrote to do this is called cukewriter. He describes how to use it in pretty good detail on the github page for the gem. I hope this will work for you, too.
